Easy ordering, even more beautiful seeing it in person
Shipping was fast just 2-3 days, everything arrived as expected and in good shape. Assembly was easy after watching the videos a few times, hardest part was seating the tires on the rim (setup with included tubes). I’m new to SRAM so a bit of learning curve threading in the cassette far enough to have sufficient clearance for the highest gear/smallest rear cog)…got it done.
My only concern are the brakes, seems a lot of travel on the levers for new brakes (over an inch or more)…may need to bleed the brakes? I’m contacting support to see next steps.

Awesome Machine
I looked at a ton of fat bikes, found a Crestone one size too small for me but on a big sale. Thankfully I looked on here and used the custom bike builder. I got exactly what I wanted, the newer Mastodon fork, and the weight shown on the builder was accurate! Totally blown away by this bike. As a Tig welder I really appreciate the effort they put into the frames they are beautiful. To top it all off, there is an integrated dropper port in the seat post! Couldn't get any better and the price is amazing. Would drop off the wine basket for the holidays if I didn't live on the other side of the country. They also answered all questions throughout the process. I am definitely not a bike builder expert haha.
